At least 20 people were killed in violent clashes on Friday between Christian and Muslim mobs in Taraba state, prompting a round-the-clock curfew, an aid worker has said.

“We have recovered 20 bodies from the violence so far,” the source, speaking on condition of anonymity on Saturday, said about the unrest in the town of Wukari, some 200 kilometres (125 miles) from the state capital Jalingo.
